Breast Cancer Death Rate Dropped 58 Percent Over 44 Years in U.S.

Between 1975 and 2019 in the U.S., improvements in breast cancer screening and treatment resulted in a 58% reduction in breast cancer mortality, decreasing from an estimated 64 deaths per 100,000 women to 27. This is according to research published in JAMA. This decline was attributed to treating metastatic breast cancer (29%), screening (25%), and treating stage I to III breast cancer (47%).

Simulation models indicated that the most significant improvement in survival after metastatic recurrence occurred between 2000 and 2019. The findings highlight the contributions of screening and various treatments in reducing breast cancer mortality over the studied period, with specific impacts on different cancer types.
